'IMPROVEMENT iN wiNnow-FRAM'ES.

The Schedule referred to tu these Letters Patent and making of the same.

I, WILLIAM H. GRIFFIN, of Springfield, zinipden county, Commonwealth o f Massachusetts, haveinvented an Improvement in Windows, of whichlthe following is a. specification.

Nature and Objectsl of the Invention.

- My invention 'consists iu liinging the side o f the wiiidow-jamb in such a manner that the sash containing the glass can be taken out or returned to its place by simply pushing one side of the window against-said hinged jainb until the other sash clears the bead of the window, when it can be entirely withdrawn. '.lhe windows can be removed from their placesfor the pui'- pose of cleaning them, or of securing better ventilations with little more ti'ouble than -is ordinarily em- `ployed iu raising or vlowering them; also, from thejaiiibs being hinged, there is no possibili-ty ofthe s'ashes being tootiglit in the jainbs to be easily raised or lowered from their swelling from moisture or other causes.

Description of the'Accoiiipang/z'ng Drawing,

Figure IIshows a. side elevation, with the jamb entirely uncovered to show the manner in which it is hinged.

Figure II shows a view in whichfthe hinged jamb is swiiiigback to permit the withdrawal of the sasln Figure III is a detail view oil the catch'in the sash holding the weight-cord; and

Figure IV shows a front view of one 0i' the hinges.

General Description.

A is the hinged jamb, which is attached by the double hinges B at its top and C at its lower end, to the ends of the jamb above and beneath, which are fixed, and which are long enough to afford a4 secure fastening to the hinges which are screwed to them.

These hinges B and G, each havingtwo centers,

permit the jamb to be swung outward and upward,

' and as the cord L, attached at one end tothesasli of `the window, and at the other to the 'weight' W,' passes over a pulley in the swingingjamb A, the

" janib A, when swung out and up, has not only its own weight but that of the weight W which rests against it, to return it to its place iiishwith the fixed ends of the jainh to which it is attached. Y', Thehinge B has the flange 1), andthe one C the fiaiwe c which corne a ainst shoulders ou the lower parts ot the hinges, so as to form acontinuous sliding-I surface for the sash.-

. In a window containing two4 -szishes I placeone swinging jamb upon one side', and the other upon'` the other. l Y I Iii order'to remove easily and at once the sash Vfrom the weight-cords, when it has been removed from the. 'Y

A windowehinge, consisting .of the swingingv jarnb A, double hinges B and O with their flanges b and c, the parts being constructed and arrange substantially in the manner and-'for the purpose shown and de,-
